The former New Edition singer, who is promoting his autobiography Every Little Step, due next week, sat down for a wide-ranging "20/20" interview that aired Tuesday night.

Bobby Brown is setting the record straight about allegations that have trailed him for decades.

The "Every Little Step" singer detailed all of the big steps of his own life in a tell-all interview with Robin Roberts for "20/20." The most prominent subjects of the conversation involved his late wife, Whitney Houston, and late daughter, Bobbi Kristina Brown, both of whom were found unconscious in bathtubs.

Though he's been blamed for getting the late Grammy-winning singer involved with drugs, Brown claims that is not the case.

"It wasn't me," he told Roberts. "I take my part and I take it hard for me even being a part of it, but we all have our own minds and some of us are stronger than others."

Remembering Bobbi Kristina Brown

In his new memoir, Every Little Step, Brown describes seeing his ex-wife hunched over a bureau snorting a line of coke before their wedding, which she allegedly offered to him, but he says he did not accept. "It was the first time I actually had saw her do drugs," he recounts. "It only made me love her and want to protect her more."

"I always made a point to not let her see me or my wife in that type of situation, in that type of feeling," Brown said. "It's hard when, you know, you're doing it every day."

However as their erratic behavior on "Being Bobby Brown" escalated and Brown's arrest record grew, their personal and public personas collided, giving way to Houston's infamous "crack is whack" claim during an interview with Diane Sawyer.

"We both needed to get away from what we were doing," Brown said of the interview. "[There] was no reason for her to be on television at that time."
